Be itknown that 1, CHARLES V. l/V RREN, a citizen of the United vFatates, and a resident of Cambridge, in the county of Middlesex and State of llffassachusetts, haveinvented an Improvement in Lubricators for Elevator Guide-Rails, of which the following, description, in connection with the accompanying drawings, is a specification, like I 3 in a manner well known to those skilled I characters on the drawings representing lik parts.

My invention relates to lubricators and more particularly to devicesfor lubricating I elevator or sin11largu1des,and has in View thereof, while its scope will be more par; out, in j the 'appended ti'cularly- :pointed clalms.

Referring to the drawings and to theembodiment of 'my invention therein shown: 1 represents a portion ofan elevator car of any usual. construction having a shoe 2 arranged to slide vertically upona guide rall in the art. A lubricant reservoir or can 4 is ,mounted on the elevatorcar 1, herein short a distance thereinto.

The: lubricator reservoir or can-dis mounted upon the sup.- port 5 in any suitable manner as by providing said reservoir. with a laterallyexQ tending. tubular nose 6,fixed with respect to the reservoir and preferably extending" a Herein the nose or guide 6 .is clamped to the support 5 by means of a yoke 7," there being provided 'bolts8, 8 passing through'the yoke and sup- ,porflabove and below. the nose" and serving to draw the, yoke :toward the support, thus Sp ecification of Letters Patenit. l

of cotton, whichI have found feeds the oil i very satisfactorily "by capillary action,

This wick extends upwardlywithin the res- I tube 9 into engagement with the] guide frail?- ervoir and thence laterally through thewick 3 and is constantly yieldingly urged against saldgulde railby suitable resilientineansg hereln'a' spring 11; In'the form herein shown this spring is of thejhelica-l type and encircles the wickjtube 9.--Where itprojeots beyond the nose 6.. One'end of this spring bears against the outer end of thenose and .j I at the other against a suitable abutment on f or boss 12 secured to theouteriendo-f the f wick. tube I the wick tube, herein consisting of a collar any suitable manner as by soldering.

VVhen'thelubricator is mounted upon the elevator carthe pr0jection 13 'will'be placed substantially in a cenitral position in the some so as to be capable of movingin either direction. It will be. evident. that the spring-will serve to main-, tain the outer end of'the wick incontact with theguide rail, and will compensate for rregularities in. the guide rail. Some guide rails are. more or less irregular or out .ofl

true and it, will accordingly be evident that taining the Wickvincontactwith the-rail re- I suitable provision must be made for main gerdless 9 ny th.irregulari-tiesthat may exist.

finto its tube but permit; it tobe withdrawn While I have herein shown and described one form of my invention for illustrative purposes and have disclosed and discussed in detail the construction and arrangement incidental to one specific application thereof, it is to be understood that the invention is limited neith r to the more details or rela tive arrangement. of parts, nor to its specii'c application herein shown, but that extensive deviations from the illustrated form or embociment of the invention may be made without departing, from the principles thereof. r p

Having thus described my invention, what I claimis: J

'1. The combination of an oil can having a nose, a, cylinder adapted to reciprocate within said nose, said cylinder having an enlargedend, a spiral spring arranged between the end of the nose and the enlarged 1 end of thecylinder.

2. ln lubricator for elevators, in combination, a nose, on one side thereof, a member slidable within said nose and having a boss on the end thereof, and resilientmeans contacting the nose and'the boss and tending to hold the member'outwardly.

3. Ina-lubricator for elevator guides, a nose having a slot therein, a member extending beyond said nose and having a pro.- jection thereon slidable within said slot, a boss upon said member, and a spring mounted upon saidmember between the end of the nose and the boss tending to keep the projection in one endof the slot.

' 4. In a lubricator for elevator guides, a nose projecting/through one side of the lubricator and having a slot therein, a cylindrical member within said nose extending beyond the same and having a projection engaging said slot and also having a boss upon theouter end thereof, a spiral spring mounted upon said cylindrical member and located between the nose of the lubricator and the bossof the said member, and a wick adjustably secured in said member.

' 5. In a lubricator for elevator guides, a

a lubricant cup adapted to be secured to'the elevator, an extensible member secured to he'cup' and having a wick therein one end of which extends into the cup and means for causing the other end of the wick to engage the elevator guide rail regardless of the distance'between the said rail. r p
